My wife and my wallet permitting...

Hi guys,

I was thinking to go big this time....
Top flight P47 size 60 320$
TGY AerodriveXp 90 SK Series 50-65 270Kv / 2100W 40$
TURNIGY Plush 80A w/ UBEC Speed Controller 40$
Turnigy 5000mAh 6S 35C Lipo Pack 100$
and i got all the servos...
around 600$ to get it up in the air
What do you think? that would be my first conversion to electric...
What's your next plane???

Fab, i've got the Hangar-9 .60 size P47, GREAT flying bird.

I have the Turnigy 50-65B-350 motor on mine, spinning a 16X10E prop on 6S.
It's enough power for scale flight, but I wouldn't mind a bit more speed. This setup only draws about 1150 Watts, right at 50 Amps at full throttle.
I'm going to go up to a 12 pitch prop, should be well within my power system's capacity.

I don't think the 270kv motor will give you a high enough RPM on 6S, you might want to run 7S or 8S with that motor, depending on which prop you run.

If I had it to do over, I think I would have gone with the 400kv version. I do have a 50-55-580, I'm thinking about trying that on it just for kicks. I always try to run more power than I need .

thanks vega, i was thinking to for a 4 blade that's why i chose 270kV what do you think of this TGY AerodriveXp 90 SK Series 50-65 380Kv / 1820w ?
I know but H9 doesn't have flaps and i hate those servos sticking out of the tail

Fab I too have the H9 P-47 .60 and love it, but I would get the top flight if I were buying a a p-47 right now. It has flaps and I think it has a covered battery bay which is nice. I had to make my own, pain in the a#@.

The SK motor should work ok too, just keep in mind, just because the specs say 1820 Watts, that doesn't mean you will get that much out of it. It all depends on the voltage you run it on and the prop you choose.

The prop 800 suggested would most likely work excellent on that plane, but you will want to monitor Amp draw closely with a Wattmeter when you set it up to make sure you're not overdrawing it. That prop would be good for the SK motor on 6S, I would guess you will probably be near the 1700 Watt range or so.

On a side note, just be careful of the SK motor throwing magnets. It is kinda common with the larger Turnigy motors. I do have a 50-55-580 SK motor that puts out 1533 Watts spinning a 11X8.5X3 prop on 6S, and it hasn't thrown any magnets as of yet.

My 50-65B-350 threw magnets during test runs, but the replacement they sent me has been great so far.

The reason I choose the H9 p-47 was I liked its covering better and I had seen one fly at my clubs field.

top flite for both--I would go with the 47 if its your frist warbird. I have a blue nose and it looks like they did some work to make the second batch better, but its a handful on takeoff and landing and very easy to be made too heavy. I have heard aboslutely nothing but good about the top flite jug, and mustang other than the retract mounts on the mustang which can be fixed rather easily.

As far as the hanger 9 jug i have heard nothing but good--but the top flite is very very scale and IMO gets you more bang for your buck.

i really think that i am going for the topflight jug, It is not my first warbird...i have experience with WWI planes, green model camel and GP Fokker DRI, DVII and Kyosho FW190 and Spitfire but topflight P47 is my first conversion and would be the biggest ever built
